Repeat Flat Batteries — Walsgrave fleet jumpstart & Diagnosis
Flat again in Walsgrave? We measure quiescent current and alternator output before selling anyone another battery. Mobile Fleet & Business Jumpstart, 24/7.
A healthy vehicle should draw around 20–50 milliamps once everything has gone to sleep. A faulty module, an aftermarket alarm or a stuck relay can pull ten times that, which flattens a good battery in two or three days.
Business account jumpstart and battery replacement across Walsgrave — priority response, single monthly invoice, no per-job admin, no chasing drivers for card payments.
Fleet vans die from parasitic drain more than anything — trackers, dashcams, tail-lifts, refrigeration. We identify the drain, not just recharge the battery.
How a drain is actually traced
- Alternator output is checked under electrical load with headlights, blower and heated screen on, not just at idle.
- Circuits are isolated fuse by fuse to locate the offending module rather than guessing at the usual suspects.
- Parasitic drain diagnostics standard — trackers, dashcams, refrigeration, tail-lifts, aftermarket wiring
- Fleet & Business Jumpstart work here is judged against the vehicle's own specification rather than a generic pass mark.
Drain faults found nearby
Recent job nearby: a car in Walsgrave on its third battery in two years. Drain measured at 480mA, traced to a boot latch microswitch keeping a module awake.
Recent job nearby: a vehicle off M6 J2/J3 flattening weekly. Alternator produced 13.1V under load — replaced the charging fault, kept the original battery.
Usage patterns that flatten good batteries
We see this pattern often with cars used for short journeys around Walsgrave — a 10-minute trip never replaces the charge that starting consumed, so the battery slowly sinks regardless of health.
Locally that means the streets between Walsgrave and Coventry, with access via M6 J2/J3 and M69 and a practical radius reaching Coventry (~3 mi) and Nuneaton (~9 mi).
Where we test
As a neighbourhood of Coventry, Walsgrave is covered alongside its parent town, so a battery keeps going flat call from any of them routes to the same engineer.

Repeat flat battery questions
Q.What if a driver is stranded outside our depot?
That's what account customers get priority for — one call from the driver, we handle it and bill your account, no card payment at the roadside.
Q.Is a parasitic drain always an electrical fault?
No. Sometimes it is an aftermarket dashcam, tracker or alarm wired to a permanent live. Those are the easy wins and we find them first.
Q.How long does drain testing take?
Allow around an hour. Most of that is waiting for the vehicle's modules to sleep — rushing it produces a meaningless number.
Q.Could short journeys alone be the cause?
Yes, and it is more common than people expect. If that is what the readings show, the fix is a conditioning charge and a change in usage, not another battery.
Q.Do you cover Walsgrave and the CV2 area for this?
Yes. Walsgrave is inside our routine coverage from Oldbury via M6 J2/J3, roughly 3 miles from Coventry. We cover it alongside Coventry and the surrounding streets.
Q.Can you supply and fit batteries at trade price?
Yes — Yuasa, Varta, Bosch and Exide at proper trade rates for account customers, fitted on your yard with OBD coding included.
